fdo#77979: sw: RTF export: write non-ASCII font names encoded
Currently font names like "微软雅黑" (Microsoft YaHei) are
written as "????" in the RTF export; to avoid that, set the \fcharset
of the font entry to something that at least is able to encode
the font name and alternate name.
This requires a new function since the existing
rtl_TextEncodingToWinCharset was changed in
b88fe998ce8c80d7629fe70118311096615d959d to return "default" 0x01
(for OOXML) which is quite unhelpful for RTF.
This is not entirely satisfactory, as of course that is no guarantee
that the encoding can represent all of the actual text that has the
font applied; hence there are some \'3f in the fall-back encoded text
of the heading of the bugdoc, which indicates that the detected
Shift-JIS is insufficient and GB-2132 would be required; but it's not
obvious how to do better here without iterating over all the text
twice, and that still leaves the possibility that all text that has a
particular font applied cannot be represented by a single non-Unicode
encoding.
But since we always write text as the \u Unicode + legacy fall-back,
this should not be a big problem since modern RTF readers will simply
read the Unicode.
